Own this Launch?

StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 16 April 2026; the live site may have changed since.

CalcPocket has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Hacker News on April 15, 2026. The site is hosted on HostPapa in the United States, with a domain registered 3 months before launch. Our crawler found 10 technologies on this site, covering advertising, analytics, consent tooling, and DNS providers. The stack includes Google Funding Choices, Apache, and cdnjs.
